Patent GB-2075087-A (GB)
Title: Shear thickening fluid
IPC: C09K8/516
Filed: 1980-09-24
Abstract: Shear thickening fluids which comprise a water swellable granular material (clay) present in sufficient quantity so as to be capable of rapidly forming a stiff paste, having a strength of at least 2000 lbs/ 100 ft.2 upon interaction with the aqueous phase used, a nonaqueous hydrophobic material comprising a hydrocarbon material and a surfactant and/or a strengthening agent, and an aqueous solution comprising water and water-soluble/water-swellable polymer, wherein the granular clay and water-polymer solution are kept separated by the intervening hydrocarbon-surfactant composition. Discrete particles of granular clay are encapsulated in the oil phase and individual droplets of water-polymer are also encapsulated in the oil phase resulting in an oil continuous phase composite. The intervening oil phase prevents the interaction between the water-polymer and the granular clay phases and results in a stable, non-reacting, pumpable composite until such time as the oil envelope is ruptured by application of a sufficiently high shear force. Upon such rupture, the materials interact resulting in the semi-rigid high strength paste.

Title: Z-axis flexure suspension apparatus
IPC: G11B5/48
Filed: 1980-09-15
Abstract: Magnetic transducer head assembly (30) particularly suitable for use in data transfer systems of the type using a non-rigid planar rotating magnetic recording media (22). A flexure support structure (50) operatively carries a transducer (40) for movement in a manner characterized by resilient movement in a Z axis direction and very limited rotational motion about X and Y axis coordinates orthogonally disposed to the Z axis, but which prevents other modes of movement that can give rise to data transfer errors caused by mispositioning movement of the transducer data transfer surface (40a) relative to the rotating recording media surface (22a). A plurality of flexure axis members (51b) support the transducer (40) in suspended manner for such controlled movement within a protective housing (31), with the data transfer surface (40a) of the transducer being operatively exposed. The flexure head assembly (30) is combined with both single and double-sided magnetic data transfer systems to provide improvement in both transient and steady-state operation of such systems.

Patent GB-2101023-A (GB)
Title: Method of rolling metal strip
Inventor: YAMAMOTO HIROYASU
IPC: B21B1/22
Filed: 1981-06-09
Abstract: Three or more work rolls 11-14 of a strip rolling stand are arranged in a common plane so that passes are defined between adjoining work rolls, and the strip follows a serpentine path through them. The work rolls are driven so that successive rolls of the roll stand rotate with increasing peripheral speed as the exit end of the roll stand is approached. In at least one of the pairs of the work rolls, the peripheral speed of the higher-speed work roll is greater than the speed with which the strip leaves the roll pass formed by the relevant pair of work rolls, whereby that work roll no longer has a neutral point in the region of its arc of reduction. In this way the metal strip can be rolled with high reduction without the tension on the strip leaving the roll stand exceeding the breaking strength of the strip and without occurrence of strip slackening or skid marks. <IMAGE>

Title: Electronic data storing apparatus
IPC: G04G11/00
Filed: 1981-11-11
Abstract: An electronic memoranda device especially suitable for the retrieval of stored data with low energy consumption is provided. In the electronic memoranda device, days, times, and schedules, and the like, are stored in a data memory. At regular intervals a key portion of these stored times is compared with a key portion of a current time signal outputted from a timekeeping circuit. When the key portion of time data read out from the data memory coincides with the corresponding portion of the currently outputted timekeeping signal, the entire data stored in memory is scanned for coincidence with the complete timekeeping signal. Coincident data is outputted for display. When the initial survey of the memory indicates that no data is stored corresponding to the key current time unit provided by the timekeeping circuit, the inspection operation of the memory is interrupted until the occurrence of the next time unit wherein inspection of the memory is repeated.

Title: Pulse circuits
Inventor: RICHARDSON ROBERT
IPC: H03K3/57
Filed: 1983-01-22
Abstract: A pulse circuit for use with a radar transmitter is arranged so that a sequence of very closely spaced radar pulses can be generated, with the interpulse spacing being shorter than the normal recovery periods of the associated pulse generators. A number of separate pulse generators are linked to a magnetron via a common pulse transformer; a fast acting diode 10 in each pulse generator isolates it from the remaining pulse generators, and the charge left on the capacitance 20 of the magnetron at the cessation of a pulse is used to enable the diode to revert rapidly to its blocking state. This discharge of stray capacitance also helps the magnetron to recover more quickly. Winding 13 is used to reset the saturable reactor 11 when its magnetic flux becomes saturated. <IMAGE>
